The presence of Nabalus acerifolius Maximowicz in China, given by W. Wang and C. Y. Li (Fl. Pl. Herb. Chin. Bor.-Orient. 9: 419. 2004) under the name Prenanthes acerifolia (Maximowicz) Matsumura, appears most unlikely. The bluish white flowered species with palmately 3-7-lobed, long petiolate, mostly basal leaves, is otherwise considered as endemic to Japan.
